目的了解宁夏银川河东机场鼠类密度、季节消长情况及种群分布,为防控鼠害、预防鼠传播疾病提供科学依据。方法采用夹日法、昼夜弓形夹法和5m夹线法在机场不同地点进行调查。结果①共布放有效鼠夹7463夹次,捕获鼠类32只,经鉴定隶属于啮齿目-鼠科-家鼠属-褐家鼠占21.9%;小家属-小家鼠占31.2%;松鼠科-黄鼠属-达乌尔黄鼠阿拉善亚种(简称阿拉善黄鼠)占34.4%;仓鼠科-沙鼠属-子午沙鼠占12.5%,黄鼠为优势种。②生活区(家栖鼠)鼠类平均密度为0.28只/100间,候机楼未捕获到鼠,停机坪(野栖鼠)鼠类平均密度为0.22只/hm2。③鼠类季节消长家栖鼠以4、10月份为高峰期,野栖鼠以6月份为高峰期,在1、2、9、11月份鼠密度为零。结论银川河东机场鼠密度较低,鼠种构成相对简单,达到基本无鼠害机场,今后还必须持之以恒,坚持科学灭鼠,严防疫情输入,巩固灭鼠达标成果。
Objective To understand the rodent density, seasonal fluctuation and population distribution of Yinchuan Hedong Airport in Ningxia, and provide a scientific basis for the prevention and control of rodent diseases and the prevention of rat-borne diseases. Methods The methods of sandwich method, diurnal method and 5m sandwich method were used to investigate at different locations of the airport. Results ①A total of 7463 clamps were placed and 32 were captured, 21.9% of which were Rodents - Rodents - Rattus - Rattus norvegicus; 31.2% of them were Small Squirrels - Pythbus - Daurian ground squirrel Alzheimer’s (34.4%); Hamster - Gerbil - Meriones accounted for 12.5%, gibraltar is the dominant species. (2) The average density of rodents in living area (domesticated rats) was 0.28 / 100. The average density of mice in the terminal was 0.22 only / hm2 in the apron. (3) Rodent exponential growth of domestic animals in April and October as the peak, wild rats in June as the peak, in January, February, September and November, the mouse density is zero. Conclusion The rodent density in Yinchuan Hedong Airport is relatively low. The rat species composition is relatively simple and reaches basically no rodent airport. In the future, we must persevere in scientific rodent control, prevent epidemic situation from entering, and consolidate the results of rodent control.
